Support for up-arrow previous prompt history, and control-keys

[mikecvet]

It would be great if there was a way to support input history with the Text, which iterated through prior entries through the up-arrow.

Also, on Mac OS, cntl-D seems to just input 'd' rather than a shell-like exit command, though cntl-C quits properly.

For me, not only ctrl+D does not properly send end-of-input, but ctrl+C also does not quit. Other control keys like ctrl+A (that's jump to begining of the line in bash) and ctrl+K (kill from cursor to end of line in bash) also just enter the characters as if ctrl was not pressed. It would be nice if those worked out of the box, at least when using bash which usually supports these kinds of controls.
